CentOS7 IP address configuration

In the previous version of CentOS 7, you can set your own static IP address through Setup, but starting with CentOS 7, it seems that this function has expired, if you want to configure our server a static IP address, we have to modify the configuration file to achieve this requirement

No more nonsense, let's see how to configure the static IP address for CentOS 7

Enter the path of the configuration file to configure the network:

Vim/etc/sysconfig/network-scripts/ifcfg-em1

Then modify the content inside, the content needs to be modified only two:

Bootproto=static # Here is the default DHCP

Onboot=yes # The default here is no

Then add these at the end of the file:

ipaddr=192.168.0.2 #这里配置你所需要配置的静态IP Address

netmask=255.255.255.0 #这里是子网掩码

gateway=192.168.0.1 # Gateway

dns1=202.106.0.20 # DNS Address

Finally, restart the NIC

Service Network restart

Now, check your IP address, have you changed it?

Ifconfig
